There are backpacks currently being offered on Ebay UK by a certain an.walker. An example is at:
http://cgi.ebay.co.uk/ws/eBayISAPI.d...e=STRK:MEWN:IT
Do not even be tempted to buy one! It is implied that this backpack is specifically for laptop use. There are no compartments inside, let alone a dedicated padded one for the computer. This is just a cheap, ordinary backpack with nothing special about it.
Specifically the seller lists that the backpack has:
Ergonomic back pad system with 3 section lower back lumber support.
Central Spinal system.
Anti-nipple rub padding.
Fully adjustable pack height system.
None of these features are present and, furthermore, claims that it is:
"totally 100% waterproof, with waterproof zippers as used with divers dry suits and all the seems are heat tape sealed, therefore if the situation arises where your out in the field and your backpack is dropped into either a river, lake or the sea this pack will not leak or absorb any water or moisture. It also comprises of 22% buoyancy aided closed cell foam in the backpack back pad, shouulder and chest straps and dividing compartments, which provides upto 18lbs or 9 kilos of total buoyancy lift."
are blatantly ludicrous upon even a cursory examination of the item.
I have only contacted the seller to express my disgust and to inform him that I'll be keeping the item so that photos can by provided for future buyers and for ebay's fraud investigators.
